According to scientists' research, the month in which babies are born could affect them in some ways.
Babies born in spring get sick easily. Children born under Aquarius may be less clever than those born in other seasons. They may also have shorter lives than those born in autumn  Scientists believe many of the differences can be explained by the mother's exposure to sunlight in pregnancy(怀孕).  Sunlight helps lead to the production of Vitamin D in the body. The lack of this in the first months of life may have a bad effect on mental and physical health.
Vitamin D, called the "sunshine vitamin", is known to help regulate(调节) thousands of genes during development, according to a study of more than two million people. So Vitamin D has a good effect on health  This study showed that people born from April to June had slightly shorter lives than those born in October, November or December. Similar studies in the USA showed that people born in autumn lived about 160 days longer than those born in spring.
Professor Russell Foster, an Oxford University neuroscientist on seasonal biology, said the conclusions were surprising and interesting. He added, "These are small effects but they are very, very clear. I am not giving voice to star signs and they are just for fun. But it is true that we are affected by our season of birth."

Two weeks ago, Ruichang City in Jiangxi Province was hit by an earthquake measuring 5.7 on the Richter scale(里氏震级). It killed 18 people and left hundreds homeless.

   Earthquakes are one of the most deadly natural disasters(灾难) in the world. They happen more often than you would expect.

   In the 24 hours after you read this, 400 to 500 earthquakes will shake the earth. You won't notice most of them because you live in a relatively(相对地) safe area or the quake is too far away or because the quake will be too small to notice.

   Earthquakes are caused by sudden breaks in rock masses(群) deep in the earth. Rock masses are always under very high pressure. If the pressure in a certain area become too much and the rock masses break, an earthquake happens. But exactly when the rock masses reach the breaking point is a mystery(谜).

   China is on the Eurasia(欧亚) plate, where earthquakes happen very often due to the earth's plates knocking against each other. Up to 17,139 earthquakes have taken place in China in the past 44 years, according to scientific research.

Once upon a time a woman found she was not easy to wake up in the morning as early as she wished. So she bought a beautiful alarm clock. These clocks are so made as to strike with loud whirring noise at any hour the owner pleases to set them.

The lady placed her clock at the head of the bed, and at the right time she found herself roused by the long, rattling sound.

She got up at once, and felt better all day for her early rising. This lasted for some weeks. The alarm clock faithfully did its duty, and was plainly heard so long as it was obeyed.

But, after a time, the lady grew tired of early rising. When she was waked by the noise, she merely turned over in bed, and slept again.

In a few days, the clock ceased to wake her from her sleep. It spoke just as loudly as ever; but she did not hear it, because she had been in the habit of not obeying it.

Finding that she might as well be without it, she made up her mind that when she heard the sound she would jump up.

Just so it is with conscience(自觉意识,诚意). If we will obey its voice, even in the least important things, we can always hear it, clear and strong.

But if we allow ourselves to do what we have some fears may not be quite right, we shall grow more and more sleepy, until the voice of conscience has no longer power to wake us.

4Why did the clock failed to stop to get the woman up later?

A. Because she was tired of getting up early in the morning.

B. Because she could not hear the clock any more.

C. Because she was too tired to wake up at it.

D. Because the clock stopped to do its duty.

A. we should always obey our clocks

B. the clock sometimes can’t wake us up as we wish 

C. It is conscience that ensures early rising not the clock

D. The voice of conscience has no longer power to wake us.

   

Amy was a dear little girl, but she was too ready to waste time in getting ready to do her tasks, instead of doing them at once as she ought to.

In the village in which she lived, Mr. Thornton kept a store where he sold fruit of all kinds, including berries in their season. One day he said to Amy, whose parents were quite poor, “Would you like to earn some money?”

“Oh, yes, ” replied she, “for I want some new shoes, and papa has no money to buy them with.”

“Well, Amy,” said Mr. Thornton, “I noticed some fine, ripe blackberries in Mr. Green’s field today, and he said that anybody was welcome to them. I will pay you thirteen cents a quart(度量单位) for all you will pick for me.”

Amy was delighted at the thought of earning some money; so she ran home to get a basket, intending to go immediately to pick the berries.

Then she thought she would like to know how much money she would get if she picked five quarts. With the help of her slate(书写板) and pencil, she found out that she would get sixty-five cents.

“But supposing I should pick a dozen quarts,” thought she, “how much should I earn then?” “Dear me!” she said, after figuring(测算) a while, “I should earn a dollar and fifty-six cents.”

Amy then found out what Mr. Thornton would pay her for fifty, a hundred, and two hundred quarts. It took her some time to do this, and then it was so near dinner time that she had to stay at home until afternoon.

As soon as dinner was over, she took her basket and hurried to the field. Some boys had been there before dinner, and all the ripe berries were picked. She could not find enough to fill a quarter of a quart.

As Amy went home, she thought of what her teacher had often told her---“Do your task at once; then think about it,” for “One doer is worth a hundred dreamers.”

7How many times did Amy figure with her slate?

   A. 3.                               B. 4.                         C. 5.                     D. 6.

A. she got ready to waste some time to do her tasks

B. she thought it was a waste of time to do her tasks

C. she liked to waste time when should do her tasks immediately

D. she was not ready to get her tasks ready, and it’s a waste of time

9What can we infer from the story?

A. Amy’s family was very poor.

B. Amy was good at counting with a slate.  

C. Mr. Thornton was the richest person in the village.
